IMPROVEMENT IN GRAIN-SEPARATORS.

Specication forming part of Letters Patent No. 31,!14, dated January 15,1861.

To all whom t may concern: y

Be it known that I, ABRAM FANCKBONER, of Schoolcraft, in the county ofKalamazoo and State ot Michigan, have invented a certain Improvement inFan-Mills, the construction and operation of which I have described inthe following specification and illustrated in its accompanying drawingswith sufficient clearness to enable competent and skillful workmen inthe arts to which it pertains or is most nearly allied to make and usemy invention.

My invention consists in thel arrangement and combination ot' a hopper,screens, and receptacles, as hereinafter described, for the purpose ofseparating tine seeds from the coarse and the different grades of tineseeds from each other immediately after their entrance into the mill,after which the large grains are cleaned by the action of the fan duringtheir passage over and through the larger screens, which are placedlower down in the mill, as I have more fully set forth in the following`description and illustrated in the accompanying drawings.

In the said drawings, Figure 1 is a side elevation of a tan-mill. Fig. 2is a vertical Iongitudinal section made by a plane passing through thecenter of the machine. Fig. 3 is a vertical transverse section showingthe parts to the right-hand side of the line a; a: in Fig. 2. Fig. 4 isa vertical transverse section showing the parts to the right-hand sideof the line y y, Fig. 2.

1 is the hopper at the top of the' mill, into which the grain to becleaned and separated is poured, its opening in the lower side beingpartly over and partly to the left of the first screen on which thegrain falls. This screen, which is represented at 2 in the drawings, ismade ot' wire, and the meshes are just far enough apart to allow all butthe plump perfeet grains to pass through. To the left of this screenwill be seen in the drawings a board 16, which extends the full width ofthe screen and slopes or inclines a little to the right, as does alsothe screen. Under the said board and fastened to it is another board 15,which is concave on the upper side and inclines in the same direction asthe said board 16 and screen 2 and in a greater degree.

3 is a second screen made similar to the drawer t) is made ot a lengthvequal to the width of the machine, and of a width sufficiently great sothat the grain in falling from the pipe 8 will not be thrown over theedges and outside of the drawer 9 by the vibratory motion of the partsto which the pipe 8 is attached.

4 is a receptacle or box under the screen 3,

which is connected by means ot the tube 5 to the box 6 on the outside ofthe case. There is an elongated opening in the side of the case betweenthe case and the receptacle 6, in which the end of the tube 5 plays. Bythe vibration of the receptacle 4, to which the tube 5 is attached, theygrain is shaken out through the tube or spout 5 into the box 6.

1l is a screen made with meshes still larger than those of the two otherscreens and inclining in the opposite direction.

12 is a screen exactly similar to screen 11, with the exception that itis inclined still more and in the same direction.

The screens 2, 3, 4, 11, and 12, the receptacles 4 and 7, and theguide-boards 15 and 16 are hung in a vibrating or shaking frame, whichis operated by a crank from the shaft on which the fan is hung.

13 is a board convex on the upper side, (although a straight board willanswer the purpose,) and so placed that its right-hand edge, as seen inthe drawings, is somewhat under the lett-handl edge of screen 12.

14 is an opening to and through which the board 13 guides or carries thegrain.

The mode of operation of my fan-mill is as follows: The grain to becleaned being placed or poured into the hopper 1, it passes through theopeningin the bottom of said hopper and falls upon the board and screen2. The part the grains of which are small enough to pass through thescreen 2 falls partly on the screen 3 and part-ly on the board 15, andthence to the screen 3. The screen 3 separates all the smaller seedswhich fail upon it fromy the larger kinds, the smaller ones failingthrough the screen 3 and into the box 4, whence they are conveyed bymeans of the spout 5 to the box 6, whence they may be removed atpleasure. Those grains or seeds which are too large to pass through thescreen V3 pass over it and into the receptacle 7. Thence by means ofpipe 8 theyr slide into the drawer 9. The large plump grains which wouldnot pass through the screen 2 pass over it and fail on the screen 11,where they are first exposed to the action ot' the blast from the fan.From the screen 11 they fail on the screen 12, thence to the board 13,and out at the opening 14.

From the time they fall on the screen 1l tili they arrive at the opening14 they are oontinuaiiy subjected to the action of the fan.

Having` thus fully described and illustrated my invention, I claim- Thearrangement of the screen 2, screen 3, receptacle 4, receptacle 7, spout5, pipe 8, box G, and drawer 9, in combination with the vibrating framecontaining the screens of a common fan-mili, as herein set forth anddescribed.
